ICU *is* always able to compare them as being equal, just by setting the
Even if the parameter isn't set, it uses an FCD sort (see
http://unicode.org/notes/tn5/) and canonical closure, which handles most
cases of canonical equivalence. The default is turned on for languages
where the normal+auxiliary exemplar sets contains characters that would
show a difference even with an FCD+closure sort, and can be turned on
always if desired (at some cost in performance; 30% sounds high though).
